There are thousands of LiPo battery sizes for your project, but I couldn’t find the one that fits the best. Meet the LiPo battery finder, which allows you to filter batteries based on x, y, and z sizes.
My tool contains a scraper that extracts the pages and subpages of https://www.pdbattery.com/li-polymer-battery-cells-list.html and https://www.lipolbattery.com, creating an .mjs file as a result.
The .mjs file gets imported by the web application, allowing the scraped records to be searched interactively.
